Topic: Ch 10.4 - Graphing Quadratic Equations (Day 1 of 3) Due: March 31 11:59 p.m.
**You'll be much happier if you watch the videos before working on the assignments.
Assignment: 1. Watch the two YouTube videos (attached below)
2. Download the pdf file of Textbook pages (attached below)
**There is a LOT of detail, so just skim through the examples to get the idea of what is being done
**Notice how he sets up a table of values so he knows what points to graph
3. Read through Textbook pages 579 - 583 only, and study the three examples given
4. Do Textbook pg. 587, #9 - 19 (odds)
Note: There's a great graphing website at www.desmos.com that allows you to enter the equation and then see what the parabola looks like. From there you can see the axis of symmetry, the vertex coordinates, and where the parabola crosses the x-axis. Follow these steps to get set up ...
1. Go to www.desmos.com
2. Click on "Start Graphing"
3. Click on the three bars in the upper left corner
4. Click on the fourth option labeled "Parabolas: Standard Form" and then click on "Open Graph"
5. You can then click on any line in the left hand column to manipulate the graph. Try it out; it's kind of fun!
Answers to Txtbk pg 587
Axis of Symmetry Coordinates of Vertex Parabola opens
9) x= -1 (-1, -8) Upward
11. x = -1 (-1, -1) Upward
13. x = 1/3 (1/3, 4/3) Downward
15. x = 3/2 (3/2, -7/4) Downward
17. x = -3/4 (-3/4, 7/8) Upward
19. x = 1/2 (1/2, 33/4) Downward

Week #2
Tuesday, March 31
Topic: Ch 10.4 - Graphing Quadratic Equations (Day 2 of 3) Due: April 1, 11:59 p.m.
**You'll be much happier if you review the videos above before working on the assignments.
Assignment: 1. Watch again the two YouTube videos (attached above)
**Notice how he sets up a table of values so he knows what points to graph
3. Read Textbook pages 584 and 585 and study examples 4 and 5
4. Do Textbook pg. 587, #21 - 35 (odds)
*Remember, you can use the desmos website (see yesterday's directions) to graph each question and reveal the x-intercepts. You might want to keep the answer key open while you're doing the assignment so you can easily check your answers.
The POINT of yesterday and today is to learn HOW to do all this without looking at the textbook. Make sure you're taking time to watch the videos and do some practicing. : )
Answers are attached via pdf.

Friday, April 3
Thank you for all the birthday wishes yesterday; I appreciate all of you for the good humor and joyfulness you add to my life each day ... even during these "stay-at-home" days!
Today I'll share my appreciation in the form of giving NO ASSIGNMENT. Raise a Dr. Pepper in honor of my birthday yesterday and step outside a moment, breathe deeply and count as many things as you can see that you appreciate in your life! We certainly have time to do it now! : )
Happy Friday everyone; enjoy the weekend!
